pypower.opf_costfcn

opf_costfcn(x, om, return_hessian=False)

Evaluates objective function, gradient and Hessian for OPF.

Objective function evaluation routine for AC optimal power flow, suitable for use with pips. Computes objective function value, gradient and Hessian.

Parameters:

x - optimization vector
om - OPF model object

Returns:

F - value of objective function. df - (optional) gradient of objective function (column vector). d2f - (optional) Hessian of objective function (sparse matrix).
